FIELD OF THE DISCLOSURE

The present disclosure relates to systems and methods for providingcontactless payment with a Near Field Communications attachment.

BACKGROUND OF THE DISCLOSURE

Near Field Communications, or NFC, allows for wireless communicationbetween two devices in close proximity to each other. Existing NFCdevices provide limited functionality for contactless payments using a“digital wallet,” but are restrictive and difficult to implement for anumber of reasons.

Current digital wallet solutions require channeling all transactionsthrough a defined group of stakeholders, thus increasing cost andcomplexity of each transaction. Further, current digital walletsolutions require that a mobile device be pre-manufactured with specifichardware already included, thus excluding hundreds of millions ofexisting devices from using a digital wallet solution. These and otherdrawbacks exist.

The following description is intended to convey a thorough understandingof the embodiments described by providing a number of specific exemplaryembodiments and details involving systems and methods for providingcontactless payment with a NFC attachment. It should be appreciated,however, that the present disclosure is not limited to these specificembodiments and details, which are exemplary only. It is furtherunderstood that one possessing ordinary skill in the art, in light ofknown systems and methods, would appreciate the use of the invention forits intended purposes and benefits in various embodiments, depending onspecific design and other needs. A financial institution and systemsupporting a financial institution are used as examples for thedisclosure. The disclosure is not intended to be limited to financialinstitutions only.

According to the various embodiments of the present disclosure, systemsand methods enable an approach to contactless payments using anattachment to a mobile device. Such attachments may include, for exampleand not by way of limitation, a contactless payment attachment thatplugs into an audio jack or plug of a mobile device. The exemplary useof “mobile device” throughout the application is only by way of example,and the attachment may also be used with personal computers,automobiles, televisions, gaming systems, or any other device capable ofmaking an audio jack connection. The attachment may also plug into anyjack of a mobile device capable of transmitting audio and/or datainformation, for instance, a 2.5 mm audio jack, a 3.5 mm or ⅛ inch audiojack, a multipronged audio jack, or other audio connection. Theattachment may also utilize various other connections available onmobile devices, for example, mini-USB, micro-USB, memory card slots, orproprietary ports such as, for example, a dock connector on a mobiledevice, (e.g. the dock connector on an Apple iPhone®, iPod® or iPad®).In various embodiments, the attachment approach to contactless paymentcould be provided in an online environment, whereby, for example, amobile device (such as a smartphone, audio player, tablet, or othermobile device) with an attachment according to the various embodimentscould send and receive data via a communication network sufficient toenable a contactless transaction, including a contactless paymenttransaction. The attachment could also be used in an offline manner,whereby an attachment could connect to the mobile device alone and used,regardless of whether the mobile device is connected to a communicationnetwork at the time of use. This attachment could eliminate the need fora consumer to purchase a mobile device with special hardware, enable auser to quickly and cost-effectively add contactless payment features totheir mobile device, and/or enable a user or financial institution tobypass traditional stakeholders in the payment process.

The attachment may be, for example and not by way of limitation, anaudio plug/jack based attachment for mobile devices, smartphones, orother personal digital assistants (e.g. tablet computers, music players,etc.) In one embodiment, this attachment may be operable with any mobiledevice, PDA class device or smartphone that includes an audio jack orplug. The mobile device may run software or firmware (for example, an‘app’) that works with the dongle to enable mobile payments. Theattachment may perform similar functions to existing digital walletsolutions without the trouble of strict hardware requirements or needingto use a specific intermediary for a transaction. The attachment mayprovide a pass-through or other addition to provide traditional audiofunctionality (music, calling, etc.) while the attachment is in use. Insome embodiments, the attachment may allow the pass-through audio signalto be suspended or terminated during use of the NFC portion of theattachment.

In an exemplary embodiment, the attachment may be either self-powered orpowered by the mobile device that it may be attached or otherwiseconnected to. In one embodiment, the attachment may plug into orotherwise connect to a personal computer or other source for initialprovisioning of payment credentials. In an embodiment, NFC secureelement provisioning may occur prior to issuance of the attachment. Forexample, a user may provision an attachment once the attachment isobtained by the user. A user may contact a financial institution, whowill then activate the attachment. The attachment may be activated bystandard methods, including but not by way of limitation, using atrusted service manager (TSM), Know Your Customer (KYC), through themobile device, over the phone, or other provisioning process. In oneembodiment, the provisioning may be completed before the user obtainsthe attachment. Additionally, the attachment may be provisioned formultiple financial accounts. This may be completed by provisioning thedevice to store each account or by using the mobile device tore-provision the attachment each time a purchase is desired with adifferent account. The provisioning process may securely pass encryptedcredit card details or other credentials to the secure element, such asthe credit card account number, expiration date, and other track data.

Also, an attachment may be provisioned for credit cards, debit cards,prepaid cards, or any other payment vehicle available to customers,companies, or financial institutions. The attachment may be provisionedwith or without user interaction, by the customer or financialinstitution, and any other acceptable method of provisioning. Theattachment may be provisioned “over-the-air” or via a wireless or wiredconnection. The provisioning may occur by receiving a signal from atrusted service manager (TSM).

In an exemplary embodiment, the attachment may contain an NFC antennaand secure element (SE). The SE may be a hardware chip speciallydesigned to be tamper proof. In one embodiment, the SE may be used fordigitally and physically secure storage of sensitive data, includingpayment data, health records, car key identifiers, etc. The SE may, forexample, store information related to a person, customer, financialinstitution, or other entity. In certain implementations, the SE mayalso store information related to a financial account, such as, forexample, a credit card number, debit account number, or other accountidentifier. The SE may include a computer processor or othercomputational hardware or software. As one example, the secure elementmay contain the Visa® and MasterCard® applications for PayWave® andPayPass® transactions.

The Secure Element may have the ability to securely store variouscredentials. In one embodiment, the credentials may comprise credit cardinformation. The credentials may expand beyond credit card payment infofor use over NFC. As one example, the information stored on the SecureElement may be used to auto-complete on-line checkouts or enablepurchases in other, third party applications. The Secure Element mayalso store keys, building access information, drivers licenses,passwords, loyalty card information, gift card information, transactionhistory, reward information, ATM access information, addresses,documents, pictures, or other data objects. The secure element may becapable of generating a Dynamic Card Security Code, such as a DynamicCard Verification Value (CVV3) or other security code.

The attachment may also take on multiple different form factors,including but not by way of limitation, those forms that have sufficientspace for company branding or logos. The attachment may take any shapecapable of acting as an attachment. The attachment may be made as smallas possible to be unobtrusive, or be made to have one or more dimensionssimilar to the mobile device it is attached to. In an exemplaryembodiment, the attachment may be square or have any other shape orornamental design.

In an exemplary embodiment, the attachment may include software andapplication programming interfaces (APIs) to enable remote and localprovisioning of the SE, use of NFC antenna, payments enablement, andattachment security management (e.g. long range deactivation). In anexemplary embodiment, the system may include a user interface andsoftware for an associated user access to uses of the SE, the NFCantenna, and any other portion of the attachment for use in any mannerof application desired by user or intended for by issuer. The system andsoftware may allow for multiple cards, accounts, or other informationportions to be stored in the secure element and may allow simultaneousaccess to all, or switch between the individual options.

In an embodiment, the system may include an application and/or userinterface that enables end user control for NFC transmission of paymentdata through an audio plug. The application may operate on the mobiledevice or on an external controller or device. Also, the system mayinclude APIs that allow access to the NFC antenna and secure element forenabling, disabling, locking, initial provisioning, updates, emergencyturnoff, and other operations. The attachment may be provisioned tostore information for multiple accounts, multiple cards, loyalty cards,or any other financial information. The attachment may require a paymentinitiation action enable the attachment for use. For example, theattachment may require a user to enter a PIN code or other identifyinginformation to enable the attachment for user. Additionally, theattachment may stay ‘unlocked’ and a payment initiation action maycomprise a user bumping, touching, or otherwise holding or positioningthe device near a sensor. The attachment may then ‘lock’ after use orafter a certain time after enabling. In one exemplary embodiment, theattachment may provide a physical switch, button, or other way to enableor unlock the attachment. For example and not by way of limitation, auser may press a button and enter a PIN code in order to activate orunlock the attachment. Additionally, the physical switch or button maybe used in place of a PIN code or other functionality. Additionally, thedevice may use any other type of unlocking or enabling the attachment,for example and not by way of limitation a physical gesture, touch, orswipe motion by a user. Also, the system may permit the use of acryptographic protocol (e.g. secure sockets layer) to establish a securechannel for data transmission. Upon a transaction, the attachment maytransmit information regarding the transaction through the audio jack tothe mobile device.

The application and user interface may leverage transaction data gainedfrom the attachment, wireless data connection, over-the-air dataconnection, or other means of data transmission. For example, theapplication and user interface may leverage information about theproducts and/or services being purchased, information about the accountor the account holder, information about the merchant and/or otherparties involved in a transaction, rewards information, promotionalinformation, advertising information, or other useful information.

In an exemplary embodiment, the system may provide capability tosecurely enable an attachment through hardware identifiers like the UDID(e.g. device ID on an Apple iPhone or other mobile device). For example,upon obtaining an attachment, a user may ‘pair’ that attachment with aspecific device by programming the attachment with a hardwareidentifier, thus ensuring that the attachment can only be used with thatdevice. In some embodiments, the user may ‘pair’ an attachment withmultiple devices, or change the pairing of an attachment. Also, thesystem may add authentication layers by utilizing embedded serialnumbers, location-based analytics, transaction count mechanisms, andother layers intended to avoid sniffing or otherwise compromising thesecure payment capabilities. Also, the system may lock the attachment orotherwise prevent some or all functionality if the attachmentdisconnected from an audio jack.

In an exemplary embodiment, software on the mobile device may bepartially or wholly locked or disable if the attachment is removed. Forexample and not by way of limitation, a user may not be permitted tomake a certain higher-risk financial transaction, such as a balancetransfer, without the attachment plugged in. In this way, the attachmentmay be used as an added layer of physical security for operations on themobile device.

The connection between the mobile device and attachment may serve totransmit power sufficient to power the NFC antenna, the secure element,or any part of the attachment or the entire attachment through the audiojack/plug of the mobile device. Also, the connection may include aprocess to provision a secure element through audio jack/plug. Also, theconnection may include a process for binding an audio jack/plug to oneor more specific phone identifiers i.e. UDID (Unique Device ID).

In an exemplary embodiment, the system may enable Industry Standard NFCPayment Transmission. For example, the attachment may enable two loopantennas to form an air-core transformer when placed near one another byusing magnetic induction. The system may operate at 13.56 MHz or anyother acceptable frequency. Also, the attachment may provide for apassive communication mode, where the initiator device provides acarrier field, permitting answers by the target device via modulation ofexisting fields. Additionally, the attachment may also provide for anactive communication mode by allowing alternate field generation by theinitiator and target devices.

In an exemplary embodiment, the attachment may deactivate the RF fieldwhile awaiting data. The attachment may use Miller-type coding withvarying modulations, including 100% modulation. The attachment may alsouse Manchester coding with varying modulations, including a modulationratio[[n]] of 10%. Additionally, the attachment may be capable ofreceiving and transmitting data at the same time, as well as checkingfor potential collisions when the transmitted signal and received signalfrequencies differ.

In an exemplary embodiment, the attachment may be capable of utilizingstandardized transmission protocols, for example but not by way oflimitation, ISO/IEC 14443 A/B, ISO/IEC 18092, MiFare, FeliCa,tag/smartcard emulation, and the like. Also, the attachment may be ableto utilize transmission protocols and methods that are developed in thefuture using other frequencies or modes of transmission. The attachmentmay also be backwards-compatible with existing payment techniques, forexample RFID. Also, the system may support transmission requirements tomeet new and evolving payment standards including internet basedtransmission triggered by NFC. In one embodiment, the attachment inconjunction with the software may utilize PayPass or PayWave systems toenable transactions.

In one embodiment, the attachment may include a magnetic stripe readerfor intaking data from credit cards, debit cards, gift cards, loyaltycards, identification cards, and any other object utilizing a magneticstripe.

In an exemplary embodiment, the attachment may be used to provide offersto a user. These offers may be related to transactions made with theattachment, and may include discounts, advertising, coupons, or anyother offer. The offers may also be based on transaction history,frequency, or location. The offers may also be based on a user'sindicated desires or the location of a user. Information related to theoffer may be received from the NFC antenna or over any other dataconnection. For example, a user could use the attachment to purchase apair of pants and the attachment and software, alone or in combinationwith a point of sale (PoS) device could present an advertisement oroffer to purchase a matching shirt, belt, and/or socks. The PoS devicemay transmit purchase information to the attachment, which may thentransmit the information to the phone. The software may utilize thephone's data connection to download additional information or offers. Asan example and not by way of limitation, the software may automatepost-transaction purchases via an online merchant—(e.g. cables from anonline retailer may be promoted or offered following a purchase at alarge retail store), and optionally provide a user an option to select arelated product the user would like to purchase from a list ofoptions—this may provide a reduced merchandise selection that ispresumably more relevant. Additionally, the offers may be selected byincorporating information from other sources, for example usingpreviously shown offers, past user transactions, consumer preferencesettings, geographic travel patterns, or any other information. Theoffers may also be presented when transactions are identified throughother methods, such as using scanned receipts, photographs of apurchased products, downloaded transaction records, or other ways toidentify a product or service purchased by a user. The software mayfurther present a display the effect of an offer to a user's statementin real-time, or either before or after the offer is accepted orrejected.

In an exemplary embodiment, the software in conjunction with theattachment may present information to a user. Also, the information maybe related to a recent transaction. In some embodiments, the softwaremay present a related or complementary product advertisement. Also, thesoftware may present offers or follow-on pitches related to a purchaseor transaction. Additionally, the software may provide budgetinginformation, credit limit information, alternative warranty offers,and/or alternative purchase terms such as an offer for a payment plan ordynamic term loan for a given purchase. The software may also allowdownloads and/or presentation of additional materials related to atransaction, such as receipts, warranty information, and/or productmanuals. The software may allow for real-time use of reward pointsand/or card-linked offers, (e.g. “spend [x] and we'll take [$y] off yourcredit card statement”), and may allow for a real time message broadcastnotifying the user of any savings.

In one embodiment, the software in conjunction with the attachment mayprovide budgeting functionality. The software may provide real-timeinformation to a user regarding transactions made with the attachment orother transactions, for example, the software may display to a user theamount of money spent in a given category or at a given location.

In an exemplary embodiment, the software and attachment may provide forprocess for determining an offer of installment lending related to atransaction from the mobile phone. For example, the software andattachment may, when a user makes a transaction, offer the user aninstallment loan to cover that purchase. This loan may differ from termsof any other credit account the user possesses. The offer may emphasizedynamic loan terms, such as duration, rate, or eligibility based oncreditworthiness, including links to credit card statement data andother account information as the basis for underwriting.

In an exemplary embodiment, the software and attachment may allow forsocial networking functionality. In some embodiments, a user may“check-in” to a location without making a purchase by using theattachment to transmit data to/from a PoS-like “check-in station” at alocation. Also, the software may enable social network updates,postings, or other functionality based on a “check-in” or purchase.

In another embodiment, the software and attachment may allow a number ofoptions to a user. For example, the software and attachment may providea user the option to the user to use Financial institution transactionhistory; Loyalty cards; On-line mobile commerce; Deals/Offers; Coupons;Gift Cards; Insurance Cards; Store Passwords; Provisioning for othercredit cards; Driver's licenses; Peer to Peer payments—tap twoattachments together to transfer payment; Check in when you enter thestore; Social Media check in, notice of what was bought, etc.; Productinformation from tapping on an item; Real time display of upsell andcross sell items; Warranty Upsell (optionally utilizing SKU-level data);Manuals for product (optionally utilizing SKU-level data); Receipts(optionally utilizing SKU-level data); and/or Accepting NFC payments.

In an exemplary embodiment, the attachment may not require a PoS systemto make an NFC payment. As one example, the attachment may allow a userto make contact with another attachment or like device in order tocomplete a payment. The attachment may be used in this way to allow theuser to make a transaction with a commercial entity or another user. Asone example, a user may repay an amount borrowed from another user by“bumping,” or bringing two attachments near one another.

In an exemplary embodiment, the NFC attachment may enable the paymentsthrough network data transmission over the air or through standardterminal routing. For example, the attachment may use NFC or other modeof communication as a trigger for an interne based payment, wiretransfer, electronic funds transfer, or other financial transaction.

In an exemplary embodiment, the attachment may work in conjunction witha token-based payment solution. The token may be transmitted through theabove-detailed near field communications method or by any other suitablemethod, such as barcode or quick response code scanning. Closed loopverification may be enabled by allowing a financial institution to bothissue the token and approve the transaction. Such embodiments mayprovide, for example, a token-based, dynamic solution to contactlesspayments. In various embodiments, the token-based solution could beprovided in an online environment, whereby, for example, a mobile devicesuch as a smartphone could receive a token in “real-time” via acommunication network. The token-based solution could also be used in anoffline manner, whereby a previously-provided token could be used for acertain period of time, regardless of whether the smartphone isconnected to a communication network at the time of use. In effect, thetokens could serve as single-use, or limited-use credit card numbers.

The token-based solution could also allow credit-card issuers, forexample, or any other token-issuer to set different types of parametersaround the token. For example, transaction limits, use limits, timelimits, and the like could be applied to the tokens. In other words,exemplary tokens could apply only to transactions of $100 or less,and/or only to 3 separate transactions before it expires, and only for 3days. The attachment may operate without utilizing tokens.
